About this page


For the past several years I have become increasingly interested in wildflowers that I encounter on my outings. I spend quite a fair amount of time on trying to identify the various species. I was pondering for some months to collect all the photos and information I gathered to build this page. There are several reasons for doing that. First, it can guide other fellow hikers and outdoor lovers to identify common and not so common wildflowers along the various trails and paths. Secondly, it might give some people enjoyment and pleasure to just look the photos. And thirdly, I had a great time just doing it.

The flowers are organized by alphabetically according to their family category. By reading the various sources of information I learnt that the categorization into some families is sometimes subject to change or disagreement among scientists. So, it could be that some of the flowers are actually grouped into different families depending to the source. My goal is to eventually post three unique photos of all wildflowers that will help to identify them. I am not nearly at that point to have accomplished that. I used to take mostly (only) photos of the inflorescence itself. However, many species can only be properly identified it you look closely at other features also, e.g. leaves, overall height, environment, … So, eventually I will add or replace some of the photos in an effort to provide enough information to clearly identify the flower. Under “Location” I posted the trail or area where I last saw the flower and took a picture of it. That by no means is intended to mean that you will find that species only in that area or only along that trail. It’s just that I last saw that flower here and took a picture of it. Under “Description” I tried to provide similar information about every flower that might help additionally for identification. Some of that information is expressed in botanical terms that may be hard to understand.

Having said that I need to emphasize that I am not a botanist and don’t claim to be one. That means there may be mistakes on that page. I can assure you, however, that I did my best to correctly identify the flower and provide accurate information. I found that some species are very difficult to identify, e.g. lupines, morning glories. If I simply could not properly identify the exact species they are for now just listed under their family. If somebody find errors and can correct me, please send me the reference with the proper information and I will be more than happy to update the page. The table width is set to 1400 pixels.

Lastly I want to list some of the various online sources that helped me a lot for creating this page:

  • Calflora

  • Santa Monica Mountains Wildflowers

  • Jepson Interchange

  • USDA




    Enough said… please enjoy the beauty that are the Santa Monica Mountains Wildflowers.

This is an annual or biennial herb growing a branching stem reaching 8 to 30" in height. Stem branches bear linear to somewhat lance-shaped leaves 1-8" long. The inflorescence is a wide cluster of flower heads, each enveloped in an involucre of rows of bright white phyllaries.
    Pseudognaphalium californicum
    Treasure Flower Will Rogers State Historic Park (2011) Treasureflower (Gazania) is native to southern Africa, but it can be found in other parts of the world with similar climates where it has taken hold as an introduced species, such as in California. This is a mat-forming or clumping perennial herb growing from rhizomes. Its leaves have long, winged petioles and form basal rosettes at the ground around the branching stem. The leaves have oval-shaped, dull green leaflets with woolly undersides. The plant produces large, solitary daisy-like flowers in shades of bright yellow and orange. Each flower head may be up to 3" across and has a dark reddish center of disc florets and an outer fringe of about 20 long ray florets. The ray florets may have dark spots near the bases, curl upwards along their edges, and close at night.
